Where is the line between a legitimate False Claims Act whistleblower and an opportunistic parasite?

How detailed do a whistleblower’s allegations have to be to survive a motion to dismiss and subject a defendant to expensive discovery? These questions have split the federal courts. The Supreme Court recently invited the Solicitor General to offer the government’s opinions on a petition for certiorari raising these questions. This is a strong signal that the Supreme Court will address these issues and hopefully bring more clarity to False Claims Act litigation.
